Abstract

The present invention discloses an indication method, including: receiving, by first user equipment, a first message sent by second user equipment, where the first message includes information indicating that the second user equipment supports an evolved user equipment-to-network relay function; and receiving, by the first user equipment, a second message sent by a network device, where the second message includes information indicating that the network device supports an evolved user equipment-to-network relay, or the second message includes information indicating that a cell in which the network device sends the second message supports an evolved user equipment-to-network relay. Embodiments of the present invention further provide a related device. By using the embodiments of the present invention, eRemote UE may know whether relay UE supports a layer-2 relay, and the eRemote UE knows whether a current serving cell of the eRemote UE supports the layer-2 relay.
